Questions and Answers for PT. Liquid Penetrant Testing is probably the most widely used NDT method. Penetrant Testing ( PT) - also known as liquid penetrant inspection (LPI) or dye penetrant testing - is based on the properties of surface wetting and capillary action, which causes a liquid to rise when confined to a small opening. Any PT inspection on elevated temperature (temperature other than 4C to 52C), should have special qualification on the Consumables. What Laboratory Testing Has to Offer Apabila kita melihat ke belakang, sejarah uji penetrant ini bermula ketika awal tahun 1900 an metode kapilaritas digunakan dalam industri perkeretaapian untuk memeriksa komponen mesin pada lokomotip, ketika itu uji penetrant masih disebut dengan metoda "minyak dan kapur", hal ini dikarenakan untuk pengaplikasiannya menggunakan minyak lumas hitam dan bubuk kapur. Liquid Penetrant Testing (PT), also known as Liquid Penetrant Inspection (LPI) or Dye Penetrant Testing, is reliable for detecting surface-breaking flaws in materials with a non-porous surface such as metals, plastics, glass and ceramics. All the best and be sure to follow all the steps. It is economical, versatile, and requires minimal training when compared to other NDE methods. Dye penetrant and liquid penetrant inspections are typically carried out in 6 steps: Pre-Cleaning - Parts must go through a pre-cleaning process (etch, alkaline or solvent-cleaning) before the liquid penetrant is applied. Article -6 of ASME BPVC Sec-V is the article for Liquid penetrant Testing. Joshnewfound. The basic principle of liquid penetrant testing (PT) is capillary action, which allows the penetrant to enter in the opening of the defect, remain there when the liquid is removed from the material surface, and then re-emerge on the surface on application of a developer, which has a capillary action similar to blotting paper. 230V or 460V, 60 Hz, Single Phase. Liquid penetrant inspection (LPI), also known as dye penetrant inspection (DPI) or penetrant testing (PT), was first developed in the early 1940s to detect flaws on the surface of materials. Liquid penetrant exams check for material flaws open to the surface by flowing very thin liquid into the flaw and then drawing the liquid out with a chalk-like developer. Penetrants will either include a visible dye or a fluorescent dye. 9 Daily Performance Checks for Liquid Penetrant Inspection Systems Learn more on why penetrant daily checks are important for the integrity of your LPI Systems Better Weld Inspections with Dye Penetrant [Case Study] LPT is based on capillarity or capillary attraction, where a liquid is able to flow into narrow spaces without the assistance of - or even in opposition to - external forces such as gravity. 1.2 The penetrant examination processes described in this practice are applicable to in-process, final, and maintenance (in-service) examinations. 1.1 This practice establishes the minimum requirements for conducting liquid penetrant examination of nonporous metal and nonmetal components.
